/**
* purple_cmd_register:
* @cmd: The command. This should be a UTF-8 (or ASCII) string, with no spaces
* or other white space.
* @args: A string of characters describing to libpurple how to parse this
* command's arguments. If what the user types doesn't match this
* pattern, libpurple will keep looking for another command, unless
* the flag #PURPLE_CMD_FLAG_ALLOW_WRONG_ARGS is passed in @f.
* This string should contain no whitespace, and use a single
* character for each argument. The recognized characters are:
* <itemizedlist>
* <listitem><literal>'w'</literal>: Matches a single word.</listitem>
* <listitem><literal>'W'</literal>: Matches a single word, with
* formatting.</listitem>
* <listitem><literal>'s'</literal>: Matches the rest of the
* arguments after this point,
* as a single string.</listitem>
* <listitem><literal>'S'</literal>: Same as <literal>'s'</literal>
* but with formatting.</listitem>
* </itemizedlist>
* If args is the empty string, then the command accepts no
* arguments. The args passed to the callback @func will be a %NULL
* terminated array of %NULL terminated strings, and will always
* match the number of arguments asked for, unless
* #PURPLE_CMD_FLAG_ALLOW_WRONG_ARGS is passed.
* @p: This is the priority. Higher priority commands will be run first,
* and usually the first command will stop any others from being
* called.
* @f: Flags specifying various options about this command, combined with
* <literal>|</literal> (bitwise OR). You need to at least pass one of
* #PURPLE_CMD_FLAG_IM or #PURPLE_CMD_FLAG_CHAT (you may pass both) in
* order for the command to ever actually be called.
* @protocol_id: If the #PURPLE_CMD_FLAG_PROTOCOL_ONLY flag is set, this is the id
* of the protocol to which the command applies (such as
* <literal>"prpl-msn"</literal>). If the flag is not set, this
* parameter is ignored; pass %NULL (or a humourous string of
* your choice!).
* @func: (scope call): This is the function to call when someone enters this
* command.
* @helpstr: a whitespace sensitive, UTF-8, HTML string describing how to
* use the command. The preferred format of this string is the
* command's name, followed by a space and any arguments it
* accepts (if it takes any arguments, otherwise no space),
* followed by a colon, two spaces, and a description of the
* command in sentence form. Do not include a slash before the
* command name.
* @data: User defined data to pass to the #PurpleCmdFunc @f.
*
* Register a new command with the core.
*
* The command will only happen if commands are enabled,
* which is a UI pref. UIs don't have to support commands at all.
*
* Returns: A #PurpleCmdId, which is only used for calling
* #purple_cmd_unregister, or 0 on failure.
